PROBLEM TO BE SOLVED: To provide a position estimation system and a position estimation device capable of appropriately perform the estimation of a position without special operation.SOLUTION: A position estimation system of an embodiment includes a plurality of illumination devices 10 arranged in a dispersed manner in a predetermined area, and a position estimation device 20. The plurality of illumination devices 10 each include a light source 11, and a modulation unit 12 that modulates the light from the light source 11 with position specification signals to generate illumination light L. The position estimation device 20 includes a light receiving unit 21 that receives the illumination light L generated by the illumination devices 10, and an estimation unit 22 that estimates the position of the position estimation device 20 on the basis of the intensity distribution of the plurality of position specification signals included in the illumination light L received by the light receiving unit 21. 【課題】特段の操作を不要としながら、位置の推定を適切に行うことができる位置推定システムおよび位置推定装置を提供する。【解決手段】実施形態の位置推定システムは、所定領域内に分散配置された複数の照明装置１０と、位置推定装置２０と、を含む。複数の照明装置１０は、それぞれ、光源１１と、光源１１の光を位置特定信号により変調して照明光Ｌを生成する変調部１２と、を備える。位置推定装置２０は、照明装置１０の照明光Ｌを受光する受光部２１と、受光部２１が受光した照明光Ｌに含まれる複数の位置特定信号の強度分布に基づいて、位置推定装置２０の位置を推定する推定部２２と、を備える。【選択図】図１
